A battery charging method includes: charging a battery with a charging current; and changing the charging current in response to a current change event occurring during the charging of the battery, wherein the current change event occurs when the battery reaches a threshold voltage at which an anode potential of the battery reaches a reference value.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The terminal of claim 1, wherein the IC is further configured to verify the first threshold voltage corresponding to the charging current by referring to a table in which the first threshold voltage and the charging current are stored.
4. The terminal of claim 3, wherein the IC is further configured to replace the table, in response to life information of the battery changing, with a table corresponding to the changed life information.
5. The terminal of claim 1, wherein the IC is further configured to terminate a charging interval corresponding to the charging current when the battery reaches the first threshold voltage and to charge the battery with a current that is less than the charging current in a subsequent charging interval.
6. The terminal of claim 1, wherein the IC is further configured to charge the battery with a constant voltage, in response to the battery reaching a maximum voltage, and to terminate the charging of the battery, in response to the charging current decreasing to a termination current during the charging of the battery with the constant voltage.
7. The terminal of claim 1, wherein the reference value is 0.075 volts (V) to 0.73 V.
8. The terminal of claim 1, wherein the reference value is 0.075 V to 0.2 V.
11. The power source of claim 9, wherein the IC is further configured to verify the first threshold voltage corresponding to the charging current by referring to a table in which the first threshold voltage and the charging current are stored.
12. The power source of claim 9, wherein the IC is configured to replace the table, in response to life information of the battery changing, with a table corresponding to the changed life information.
13. The power source of claim 9, wherein the IC is configured to terminate a charging interval corresponding to the charging current and to charge the battery with a current that is less than the charging current in a subsequent charging interval, when the battery reaches the first threshold voltage.
14. The power source of claim 9, wherein the IC is configured to charge the battery with a constant voltage in response to the battery reaching a maximum voltage, and to terminate the charging of the battery in response to the charging current decreasing to a termination current during the charging of the battery with the constant voltage.
15. The power source of claim 9, wherein the reference value is 0.075 volts (V) to 0.73 V.
16. The power source of claim 9, wherein the reference value is 0.075 V to 0.2 V.
